科技类最常见的话题类型有两种：1，科技产品评价及未来发展即“科技产品怎么样，以后会怎么样”的问题;具体包括对现有科技产品的评价(优劣势分析、是否合乎道德标准和对个人、企业、国家以及整个社会的影响)和自己预想以后会出现什么样的产品或现有产品会出现什么样的功能以及未来的影响。
2，科技产品作为媒介即“怎么用”的问题;具体包括现代通讯技术使人类足不出户便能操作网络购物、电视购物、网上银行、视频会议等，人类使用手机的利弊，互联网传播信息的好处与弊端，网上翻译软件盛行因此还有没有学习外语的必要。
要评价一篇文章的优劣势，首先还是让我们熟悉一下writing task 2即大作文的评分标准。
(1) task response (tr)whether all parts of the task are addressedwhether a viewpoint is clearly expressed, developed and supported.(2) cohesion and coherence (cc)whether the response has a suitable layout and logical ordering of points(文章是否条理清晰，行文有逻辑)correct and appropriate use of connectives(是否正确使用衔接词)(3) lexical resources (lr)range and accuracy of vocabulary (词汇丰富度和准确度)the correct form and spelling of the words (词汇形式和拼写正确) (4) grammatical range and accuracy (gra)the range and accuracy of tenses and sentence structure (时态和句式的丰富度和准确度)接下来，我们还是以一篇满分范文为例，看看具体怎么好在哪里，为什么会拿到了满分，我们能学到哪些知识，技巧。
题目：ve.what are your opinions on this?give reasons for your answer and include any relevant examples from your own knowledge or experience.write at least 250 words.范文：the internet has brought significant changes to our lives in recent years. yet, there remains some disagreement as to whether the overall effect of this technology has been positive or negative. while there are certainly valid arguments to the country, i personally believe that the benefits of the internet far outweigh its drawbacks. these benefits are twofold.first of all, it is an indisputable fact that the internet has revolutionized the way we communicate. despite the risk of social isolation—a problemoccasionally seen in people who spend too much time at their computer terminal rather than relating to people in the real world—most of us have benefited greatly from e-mail and internet chat programs like msn messenger. theseincredibly useful and powerful tools of communication facilitate both contact with loved ones in faraway places and global trade.equally importantly, though, the internet has placed the entire world (and all of the information in it) at our fingertips. in earlier times, conducting research entailed long hours searching library shelves. now, however, the same information can be accessed at the click of button. admittedly, not all of the information available on the internet is reliable or helpful—there is a vastamount of material online that some would consider offensive or dangerous, ranging from pornography to instructions on how to make bombs. nonetheless, i would contend that this free flow of information has generally been a very positive development.by way of conclusion, i once again reaffirm my position that the internet has had a positive impact on modern life because of its influence on communication and the flow of information. (272 words)首先我们先从tr(task response)方面分析一下：whether all parts of the task are addressed：经过审题我们发现这是一个个人观点类的作文，即what are your opinions on this? 给出你自己的观点，其要求是give reasons for your answers and include any relevant examples from your own knowledge or experience，根据自己的知识或经验给出相关的例子。
其中如果用自己的知识论证那就是道理论证，如果根据自己的经验来论证那就涉及到了举例论证。
在这篇文章的首段，作者首先论述了一个互联网极大地改变了我们生活的一个大背景，最后一句话直接的给出自己的观点，表明互联网的优势远远大于劣势。
个人观点很清晰明了。
接下来两段的论点运用了道理论证和举例论证相结合，同时也运用了让步的手法，来证明自己的观点——互联网优大于劣。
这篇文章基本上完成了题目要求的所有任务。
whether a viewpoint is clearly expressed, developed and supported：其次我们在看看作者表达的观点是否清晰，有说服力。
文章的第一个论点first of all, it is an indisputable fact that the internet has revolutionized the way we communicate. 首先,互联网已经彻底改变了我们沟通的方式，这是一个不争的事实。
关于这个论点作者是怎么来论证的呢?作者首先运用了让步的手法(尽管会有造成社会孤立的风险)。
后面作者就用到了道理论证，但是我们还是受益于电子邮箱还有网络聊天工具和远处的亲朋好友聊天。
这个论据就很有说服力地论证了互联网改变我们沟通方式这个论点。
互联网的第二个优势是equally importantly, though, the internet has placed the entire world (and all of the information in it) at our fingertips. 互联网已经把整个世界和所有的信息放在了我们的指尖。
那我们来看一下作者又是怎么来论证的呢? 首先作者运用了今夕对比，即过去时候，大家都是花费大量时间在图书馆的书架上来搜索资料的，而现在呢，只要按一下按钮，所有信息都在眼前了。
之后，作者又乐此不疲的采用了一个让步的写法(尽管很多信息是不可靠或者没帮助的)，但是作者还是很满意于大量信息流是一个积极地发展。
综上可以看出，作者的第二三段都把论点放在了首句很清晰明了，并且后面支持的论据也十分的有说服力。
那下面我们一起看一下文章在连贯和衔接方面有什么值得借鉴的吧。
cohesion and coherence (cc)：文章中句与句直接的衔接词有：yet(然而)，while(虽然)，despite(尽管)，now(现在)，admittedly(诚然)，nonetheless(尽管如此)等等，这些单词在文章段落中表示着一定的逻辑关系，这些词的实用会使段落直接更加的顺畅自然。
让我们再来一起找一找段与段之间的连接词有哪些呢?很好发现，在每段的开头：first of all(首先)，equally importantly(同样重要地)，by way of conclusion(通过总结)，通过这些词来连接上下两段，起到了承上启下的作用，这样就不会过度的太突兀。
lexical resources (lr)：这篇文章在词汇方面也有很多可圈可点之处：valid arguments 有效的论点far outweigh 远大于its drawbacks 它的缺点has revolutionized 改革social isolation 社会孤立computer terminal 电脑终端faraway places 遥远的地方entailed long hours 花费长时间offensive or dangerous 有攻击性的或者危险的ranging from? to 从?到?reaffirm 重申这些都是文章中运用的非常棒的单词，值得我们背下来并且运用到自己的写作中。
